the Draw Guide have dealt only with vector graphics. However, Draw also contains a number of functions for handling raster graphics (bitmaps) such as photographs and scanned pictures, including import, export, and conversion from one format to another. Draw can read all the majority of graphic file formats. It has a subset of capabilities similar to raster graphics programs like Adobe Photoshop or Gimp.

  • Understanding Image Formats and When to Use Them
    Understanding Image Formats And When to Use Them Are you familiar with the extensions after your images? There are so many image formats that it’s so easy to get confused! File extensions like .jpeg, .bmp, .gif, and more can be seen after an image’s file name. Most of us disregard it, thinking there is no significance regarding these image formats. These are all different and not cross‐ compatible. These image formats have their own pros and cons. They were created for specific, yet different purposes. What’s the difference, and when is each format appropriate to use? Every graphic you see online is an image file. Most everything you see printed on paper, plastic or a t‐shirt came from an image file. These files come in a variety of formats, and each is optimized for a specific use. Using the right type for the right job means your design will come out picture perfect and just how you intended. The wrong format could mean a bad print or a poor web image, a giant download or a missing graphic in an email Most image files fit into one of two general categories—raster files and vector files—and each category has its own specific uses. This breakdown isn’t perfect. For example, certain formats can actually contain elements of both types. But this is a good place to start when thinking about which format to use for your projects. Raster Images Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color.

  • Graphic File Preparation for Letterpress Printing ©2016
    GRAPHIC FILE PREPARATION FOR LETTERPRESS PRINTING ©2016, Smart Set, Inc. COMMON GRAPHIC FILE FORMATS Vector Formats .ai (Adobe Illustrator) Native Illustrator file format. Best format for importing into Adobe InDesign. Illustrators’s native code is pdf, so saving files in .ai contains the portability of pdf files, but retaining all the editing capabilities of Illustrator. (AI files must be opened in the version of Illustrator that they were created in (or higher). .pdf (Adobe Portable Document Format) A vector format which embeds font and raster graphics within a self-con- tained document that can be viewed and printed (but not edited) in Adobe’s Reader freeware. All pre-press systems are in the process of transitioning from PostScript workflows to PDF workflows. Because of the ability to em- bed all associated fonts and graphics, pdf documents can be generated from most graphics software packages and can be utilized cross-platform and without having all versions of different software packages. Many large printers will now only accept pdf files for output. .eps (Encapsulated PostScript) Before Adobe created the pdf format, PostScript allowed files to be created in a device-independent format, eps files printed on a 300 dpi laser printer came out 300 dpi, the same file printed to an imagesetter would come out at 2540 dpi. PostScript files are straight code files, an Encapsulated PostScript includes a 72 dpi raster preview so that you can see what you’re working with in a layout program such as Quark XPress or InDesign. COMMON GRAPHIC FILE FORMATS Raster Formats .tiff (Tagged Image File Format) Tiffs are binary images best for raster graphics.

  • LO1: Investigating Digital Graphics
    Name: Freya Ellis Candidate Number: 5068 Centre Number: 29335 Series: June 2019 R082 – Creating a Digital Graphic LO1: Investigating Digital Graphics Purpose of digital graphic: A digital graphic is an electronic image that can be used for a variety of different things, however the image does not always have to be used on electronic devices as it can be printed and used. Some examples of a digital graphic are magazines, posters, logos etc.. My poster will include images and pictures of popular films to create an eye catching poster that will gather the audience the client wants. The images wont be of just any movies but a wide range as this is an all inclusive film festival for people of all ages. The poster will be very high quality print using 600ppi. It will also have a .tiff image format because it is a high quality print, a big file size and has a lossless compression. With our digital graphic we must make it appealing to everybody because it is a family movie festival, so thus we need to combine the demographics of adults, teenagers and small children. This make it difficult as all of these demographics are very different and so we have to make it eye catching for younger audience but also very informative for an older audience, as well as not looking too childish as to attract teenagers. The graphic I’m going to create will be not only eye catching but also informative and show the true atmosphere that the festival will have, this means it will be simplistic yet interesting easy to read yet informative as I feel this will feel my client needs the best.

The ODA Raster DAP is also included as an appendix to military specification MIL-R-28002B . Information previously scattered throughout several standards is incorporated into this report for ease of reference. The ODA Raster DAP is analyzed with regard to both notation and intent. The motivation behind the development of the raster graphics file formats for large documents which are detailed in the ODA Raster DAP originated in a meeting between the Department of Defense (DoD) and industry experts in 1987. The Computer-aided Acquisition and Logistic Support (CALS) Office of DoD asked the large document raster industry to provide suggestions for a standard interchange file format and raster encoding scheme.

    OVERVIEW OF IMAGE FORMATS SUITABLE FOR PRESENTATION OF ART ON THE WWW ZAJy\CZKOWSKI Grzegorz, JAROSZ Bartosz, WOJCIECHOWSKI Konrad, SMOtKA Bogdan, Silesian Technical University of Gliwice Department of Computer Science Akademicka 16, 44-101 Gliwice Email: bsmolka(a).peach.ia.oolsl. qliwice.pl NAtECKAAnna, MAtECKA Agnieszka SYNOWIEC Pawet, KROL Bogdan School of Arts Katowice An important aspect of image processing is the enormous amount of data which has to be handled when transmitting digital images. The efficient transmission of images is extremally important as the image data transfer takes up over 90 percent of the volume on the Internet. In this aspect computer data compression is a powerfull technology which is playing a vital role in the Information Age. The compression of information can be devided into lossles and lossy techniques. In some cases such as text or financial data transfer only the losless algoritms can be applied. However when transmitting or storing digital images or music data, the application of losssy techniques is aimost invisible to the user, but enables a drastic reduction of the data volume. In this article we present some of the compression techniques which can be used when transmitting or storing digital images. All the formats we were able to gather are accompanied by a short description and an Internet link, which can be used when detailed information is needed. Our intention is to find the optimal compression format for presenting artistic images over the Internet. The first step of our project is the cataloging of the existing formats and evaluating their efficiency when transmitting data containing artistic features.

  • Graphic File Formats Demystified Which File Format to Choose?
    Graphic File Formats Demystified Which file format to choose? INDD JPG EPS PSD TIF CAMERA RAW GIF AI PDF PNG Who cares? You should Ask Yourself What are you going to do with the file? Is your graphic raster? Is your graphic vector? What is the difference? Raster Graphics Created with pixels Resolution dependent Scaling compromises the resolution Scaling can compromise quality 100% Scaled 300% Vector Graphics Created with paths Points, lines, shapes Mathematic equations and geometry to create art Resolution independent Scalable without loss of quality Postage stamp to billboard and beyond 100% Scaled 600% Raster Vector FILE COMPRESSION LOSSLESS (lose less) This form of data compression is an algorithm that looks for redundancy in data. For instance, a blue sky may have several pixels that are the same color of blue. Rather than write each pixel it groups them together in a “run-length encoding” to say that there are 157 blue pixels. When expanded the data remembers what and where it was and no information is lost or changed. Examples: PNG, TIF, PDF LOSSY (lousy) This form of compression gathers data that is similar within a defined tolerance and rewrites that information as the same. Original data is discarded (lost). When expanded the new data is displayed. Example: JPG Raster File Formats JPG Joint Photographic Experts Group The most common file Does not retain layers or transparency Quality of the image decreases every time the file is saved Lossy compression Best For: web, raster Not For: print Original JPG JPG saved multiple times

  • Computer Graphics Can Be Divided Into Two Categories
    5 COMPUTER GRAPHIC BASICS, WORKING WITH PICTURES 5.1 VECTOR AND RASTER Computer graphics can be divided into two categories. It is a vector graphics and raster graphics. Both types have their advantages and disadvantages, and each type is useful for other purposes. Each type uses a different "basic building block" and of course other types of files. This also means that there are programs for editing vector graphics and different programs for editing bitmap graphics. 5.1.1 VECTOR GRAPHIC Vector drawing consists of individual objects, which are rectangle, ellipse, line, curve, outline, fill, and text. All these objects are made up of curves which stores information about the starting and ending point, and the directional vector of the curve. The result is a file that compared with grid is much smaller (in terms of data volume). The advantage of vector graphics is the possibility of unlimited modifications without loss of quality. these objects can be variously magnified, rotated, etc., and the drawing remains good. (We cannot say this about the raster). The disadvantage of this format is that it is not suitable for describing complex patterns (such as images) and sometimes problematic transfer between vector programs 5.1.2 RASTR GRAPHIC A raster image is made up of small dots called pixels. Each point in raster image stores information about color. When you place the points next to each other and under each other, we get the final image. Number of points is determined by the quality of the picture. The more points is, the better. This format can be found mainly in photos One advantage is that it can display grid using complex models (photo) and also convert between raster formats is easy.
